I'm power is out :( gas ventless heat?

[Jfannin]

Ok power went out a few. AEP said 1p before its back on. My MP40 has backup power but know I'm concerned about the temp dropping to low. I have a ventless gass furnace in the same room as my tank. Should I use it or not. It about 30 outside. I'm concerned of the gas furnace burning up the O2 in the room and still deprive my reef with out Oxygen even though I have water movement.

Should be My power is out lol
